WILLIAMS. REID, OF CENTER TOWNSHIP, EMMET COUNTY, IOWA.

I?) all whom it may concern:

Be it known that I, VILLIAM S. Run), a

citizen of the United States. residing in Center township,-in the countyof Enunet and State of Iowa, have invented a new and use-' fulTank-Closure, (if-which the following is a specification. I

This inventionrelates to nnprovelnents in swill or slop tanks andreceptacles, so as to have the same odorless 1d sanitary, portable, andeasily einptiedcf contents.

The objects of my invent-ion are first, to provide a swill or slop tankand receptacle thatwillnot emit obnoxious'or unhealthful odors or gases;secondly,-a receptacle for swill, slQDS, table refuse and other wastematter that Willnot attract flies, insects and other germ carriers;thirdly, a receptacle.

that will not slop or spill in the moving of liquids from one place toanother, and that may b'ecasily emptied and disgorged of its contentswithout sputtering or soiling the operator or the surfaces about it, andto proride a neat and clean receptacle for slops and waste matter at thekitchen door or other place where it is convenient and desirable to havea receptacle for slops and waste matters for the accumulation thereofand vide farmers and the like with a clean and sanitary manner ofcollecting slops and i waste matter at the kitchen or other places ofnmking and for. the removal of same to place of consumption or disposal.

Still further objects are to simplify and improve the construction andoperation of the devices for the handling of slops and refuse u'iatter.v With tneseand other ends in view which will readily appear as thenature of the in vention is better "understood, the same consists in theimproved construction and novel arrangement of parts which will behereinafter fully descri bed and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of invention; it being, however, understoml. that no limitation isnecessarily made to the pre cise structural details therein exhibited,but that changes. alterations and modifications within the scope of theinvention may be resorted to when desired.

Fromthe drawings it. will be seen that the invention is a closed tank ofsheet metalor Specification of Letters Patent.

same air tight and without'leakage, free fron'i flies and other insectsand preventing the escape of noxious odors and gases from the contentsof the tank until such times as it'may be desired to' empty any of thecon receptacle, which is done by opening the valve on the end of tankwhich operated from the exterior of the tank by a lever. And that theremoval of any solid or compact substance or settlings is assisted by anejector swinging on the inside of the receptacle worked by a lever orhandle projecting out of the top of ,the receptacle.

In the drawings: Figure 1 represents a side elevation or view of themounted tank. Fig. 2, represents a front end elevation or view ofmounted tank. Fig. 3, represents a sectional view of valve when closed.

In Figs. 1 and 2, (A) is a metal or wood tank, or tank of other materialsupported on a frame (B) and secured by meansoi straps or rings ((1').The frame v1s mounted on wheels and provided with handles.

In the mann'erof operation, the valve H is closed by a downward movementof the lever I and securely locked by means of a notched-bar J eoming incontact. with the notched edges of the lever.-

In the top of the tank is an oblong openthe inside edges of which areThe grooved surfaces of said tracks are toward the opening. In the twoparallel tracks on the long-sides of the openingslides a lid to thetank, one end of which tits in a grooved stop at the narrow end oi theopening, when the slide is shut, and the other end oi'w-hich extends outbeyond the edge oi. the opening and slidcs ovel the outsidetop Surfaceof the tank when the slide is opened. The slide is air tight. and waterlight when closed. The contents of the tank are poured intothe abovedescribed opening.

Tn one end of the tank is out an opening.

in r, along- ()n the same end. on the outside of the hori zontal surfaceis fastened or riveted over.

the opening a cast iron piece supplied with a circular valvular openingcoinciding with the said opening in the and of the tank. The lid orvalve [I to the. opening is hinged and suspended over the opening byaxles or pins .revolvinp in elongated sockets or eyes K, in two castiron hinge posts or projeetions from the cast iron piece and over thesaid round opening. The underside of said valve is provided with araised circular plane that just. fits the opening in the casting. Aroundthis raised circular plane and on the edge of the valve If is a rubberor leather gasket which makes the valve fit watertight. The roundopening and valve are provided with. sharp cutting edges N which preventany fibrous or solid matter in the valvular opening from causing thevalve not to shut tightly. To a spindle or pin M located at a point tothe lower left of the round opening in the cast iron piece one end of alever I is fastened which lever extends horizontally across the roundopening and parallel to the end of the tank and a few inches out fromthe tank. On the opposite side of the round opening from the one wherethe lever is fastened, the lever I works up and down between the tankand a nearly perpendicular shaft J which'rests on a cast iron shoulder.Said shaft J is provided on the inside with notches or teeth and slantsslightly toward the tank. The lever I and the valve lid ll areconnectedby a small barv or connecting rod L as shown in Fig. 3 which ishinged or pinned to the valve lid and to the lever. The surface of thelever I which comes incontact with the notched bar J is also notched, sothat when the lever is pressed down in the process of closing the valveit exerts a pressure on t e connecting rod which being longer than thespace between the valve lid and the lever forces the valve H shut andthe lever I is forced against the notched bar J, the notches on thelever I and the. notched bar J securely locking the lever which lockingprocess is assisted by the inwardly inclined position of shaft J. Aslover I is being forced down ward exerting a pressure through connectingrod L on valve lid ll, the pins or axles supporting valve H andrevolving in elongated sockets K are caused to move outward in sockets Kand away from the tank thus allowing valve I'l just before being closedto hang on its hinges perfectly parallel to the round opening in thecast iron piece and then by the final pressure on the lever be pushedaccurately in place in the round valvular opening.

In the top of the tank near the end containing the valvular outlet, is asmall aperture in which is swung on an axle or pin F a rod E G, part ofwhich G is inside of the tank and the remainder E outside of the tank;The portion of this lever within the tank (indicated by dotted lines inFig. 1, is provided at the end with tines or prongs so that when the endprojecting out of the tank is pushed back and forth, the forked endcrushes and pushes through the valvular opening any solid substance thatmight have collected near the outlet to the tank.

Vhat I claim as my invention and desire to secure by Letters Patent is:

1. The combination with a receptacle hav-- ing a discharge opening, of aclosure for said opening, ears having elongated slots, trunnions carriedbysaid cover mounted in said slots and adapted to reciprocate andoscillate therein, a locking lever pivoted to one side of said opening,a link pivotally secured at its respective ends to the cover and thelever, ratchet teeth on said lever near its free end, a locking bar onthe receptacle provided with teeth to intermesh with the teeth of saidlever, the connection between the lever and cover being such that themovement of the lever will first reciprocate and then oscillate thecover.

2. The combination with a receptacle having a. discharge opening, earscarried by the receptacle having elongated slots constituting trunnionbearings, a cover, trunnions on the cover, said cover mounted on thecars by means of its trunnions engaging the slots in the cars. a linkpivotally mounted on the cover at one end and free to swing, and a leverpivotally mounted on said receptacle and pivotally connected to theother end of said link, whereby the cover is reciprocated and oscillatedby the lever through said link. In testimony whereof I atlix mysignature in the presence of twowitnesses.
